Analyzing Multicore Characteristics for a Suite of Applications on an XT5 System
Douglas W. Doerfler, Courtenay T. Vaughn · 2010
In this paper, we will explore the performance of applications important to Sandia on an XT5 system with dual socket AMD 6 core Istanbul nodes. We will explore scaling as a function of the number of cores used on each node and determine the effective core utilization as core count increases. We will then analyze these results using profiling to better understand resource contention within and between nodes.
